SHEEP-SHEARS.

Applica tion filed Apr-i121, 1887.

SPECIFICATION 'forming part of Letters Patent No. 376,233I dated January 10,1888.

Sexial No. 235.587, (No model.)

ratchet, N, secured upon the projecting endlof 5o To all whom, it may concern.'

Be it known that I, DONALD CAMERON, of Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Sheep-Shears; and I do hereby declare that the following' is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specication.`

This invention relates to certain new and useful improvements in sheep-shears of that class which are provided with a rotating cutter.

The object ofthe invention is to construct a device for the purpose namedwhcrein the rotating cutter is `operated by a spring, and to provide means for winding such spring during the operation ofcutting or shearing.

To this end the invention consists-in the peculiar construction and arrangement of the winding mechanism and the application thereof to a rotating cutter, and in the various combinations of the parts, all as more fully hereinafter set forth.

Figure lis a plan view of my improved device. Fig. 2 is a side elevation of the same. Fig. 3 is an elevation with front plate removed.V Fig. et is an elevation of the cutter and comb.' Fig. 5 is a horizontal section. Fig. 6 is a perspective of the rotating cutter-head removed.

In the accompanying drawings, which form a part of this specification, A represents the front table, and B the back table, of a suitable frame, the two plates being secured together by proper spreaders and girts, C D, respectively. Properly journaled to these plates A B is a shaft or drum, E, carrying a clockspring, F, and a drive-pinion, G, said pinion and shaft being provided with the usual ratchet and pawl and connected by a suitable chain of gear to the fan H, as in the ordinary construction ofa clock-movement.

I is a handle rigidly secured tothe plate A near one edge thereof, while opposite thereto the operating-lever Jis fulcrumed to the same plate, said lever .I being spread7 under the action of the spring K. The short arm of` this lever is connected, by a proper link, L, to a spring ratchet, M, which engages with a the spring shaft or drum E. By operating the lever l, asin using a pair of shears, it will readily be seen that the spring may be easily wound upon the drum.

At the front end of the plate B is rigidly secured a comb or finger-plate, O, the fingers of which radiate from a common center, as shown.

I is a cutter-head, carrying upon its outer face a gear-wheel, It, which meshes with and isdriven by the pinion G, the said gear and cutter-head being properly journaled between the plates A B. The under face of the cutterhead is slotted radially from the center to re-. cei-ve any desired number ot' cutter-blades S, held in place by screws a, which may also be employed to secure the wheel R upon the cutter-head.

T are set-screws tapped through the cutterhead, the inner ends ot' such set-screws resting upon the face ofthe cutter, and are employed for regulating the depression of such cutters and their relation to the comb or finger-bar.

In practice, the parts being constructed and I arranged substantially in the manner Y described, the operator, by pressing the lever .l toward the handle I, causes the spring to be wound upon the drum, which latter, through the connections named, imparts a rotary motion to the cutter-head, the cutters of which, j

being slightly depressed at their outer ends in passing over the comb, make a shear cut.7

By ntermittentlyoperating the lever J the spring may be kept wound up.

By using a iner comb or finger-bar the de- Vice can be advantageously employed iu clipping horses.

What I claim as my invention is- 1. Infcombination with a comb or fingerplate, O, a rotating cutter-head, l?,` carrying independent cutters S, said cutter-head being adapted to be rotated by a spring motor-wheel, R, and the screws c passed through said wheel and cutter-head into the cutters, substantially as described.

2. The combination, with the frame and the spring-motor, of the comb O, rotating cutterhead, cutters carried thereby, and set-screws T, tapped through said cutter-head for reguspring-ratchet, cutter P, gear-wheel R, carried latiug the depression of said cutters, substauthereby, comb O, cutters S, and the set-Screws ro tially as described. T, all constructed, arranged, and operating 3. The combination, with the frame, the substantially as and for the purpose specified.
